VectifyAI/PageIndex Hits +943 Stars Today at 29.9K: Vectorless Reasoning-Based RAG Eliminates Vector Databases

GitHub·high signal

PageIndex builds hierarchical tree indexes from documents and uses LLM reasoning to navigate them—no vector database, no chunking, no embedding. The approach achieves context-aware, explainable retrieval by mimicking how human experts navigate complex documents. Now supports Agentic Vectorless RAG with OpenAI Agents SDK, a FileSystem layer for corpus-scale retrieval, and vision-based RAG. Gained 943 stars today.
